In this question, let us first note down all the important information's that have been provided in the question. The number of people that Adam is cooking for = 14 Amount of turkey required per person = 3/4 pounds Now Total amount of turkey required by Adam to cook for 14 people = (3/4) * 14 = 21/2 So 21/2 pound of turkey is required by Adam to cook for 14 people. This weight of turkey has to be converted to gram first and then to kilogram. We already know 1 lb = 450 g Then 21/2 lb = 450 * (21/2) gram = 225 * 21 = 4721 gram Now again we know 1000 g = 1 kg 4721 gm = (4721/1000) kg = 4.721 kg So Adam needs to have a turkey weighing 4.721 gram to cook for the 14 people. I hope the procedure is clear to you.
The absolute value means how far it is from 0 and 18 it 18 numbers from 0! For negative numbers its the same |-18| would be 18 as well because it is 18 numbers from 0.
